Crossed-slot antenna array design for an Incoherent Scatter Radar and characteristic modes analysis

Abstract

This paper describes the design and construction of a crossed slot antenna array to be applied to an Incoherent Scatter Radar for measuring parameters of the Ionosphere. The slot antenna was designed and optimized with electromagnetic simulation software. An analysis of the characteristic modes of the elementary antenna of the array is performed, in order to obtain a physical understanding of the radiating behavior. A prototype of a linear crossed-slot antenna array has been constructed and measured, as an intermediate step for the development of a two-dimensional array.

Analysis of slot-based radiators using TCM and its application in MIMO antennas

“…Whenever a slot is introduced in the chassis, previous works in Refs. mentioned that new slot modes are created. Are these actual slot modes?…”

“…TCM was applied on the analysis of various different types of antennas such as wire antennas, handset antennas, printed MIMO antennas, and slot antennas . In Ref.…”

“…In Refs. , it was concluded that the new mode that appeared was a new slot mode (the name slot modes is taken from the literature). All of them rely on the existing techniques to extract the slot mode.…”

“…TCM was applied on the analysis of various different types of antennas such as wire antennas, 21 handset antennas, 22 printed MIMO antennas, [23][24][25] and slot antennas. [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] In Ref. 43, it was shown that designs made with TCM are more robust under real-environment scenarios as compared to designs made with empirical methods.…”
